Laser Tools has introduced a new kit which allows technicians to test the integrity of sealed of sealed EV battery units on many common electric vehicles.

 
EVs rely on high-voltage battery packs, typically mounted beneath the vehicle's floor, which must remain fully sealed to protect them from environmental hazards such as water ingress, road debris, and temperature fluctuations. In vehicles like the Hyundai Kona EV, Jaguar I-Pace, Kia Niro EV, and Nissan Leaf, these batteries are integral to performance, safety, and longevity, making battery integrity critical. To ensure these sealed units maintain their structural integrity, manufacturers recommend conducting a pressure test, often referred to as an "integrity test."

The Laser Tools EV Battery Integrity Pressure Test Kit (part number 8467), has been specifically designed to facilitate this essential maintenance procedure for qualified technicians. The kit enables the user (following the manufacturer’s guidelines and instructions), to perform a precise and controlled pressure test on EV battery packs, ensuring that no leaks exist in the seals, particularly along the crucial large top seal surrounding the battery’s perimeter.

The pressure test is carried out by carefully introducing low pressure, depending on manufacturer, between 20 to 55 millibar (0.3 - 0.8 psi), into the battery housing. The Laser 8467 Test Kit includes a digital manometer (pressure gauge), for highly accurate readings and ensures that the technician can monitor pressure levels safely, avoiding any damage to the battery cell packs. It’s essential to introduce pressure slowly, following the manufacturer’s guidelines, to prevent any strain on internal components.

This is a complete kit: as well as the pressure gauge it includes a pump, adaptors (for Hyundai Kona EV, Jaguar I-Pace, Kia Niro EV, and Nissan Leaf), and sealing tape to ensure all battery breather and electrical connection ports are safely sealed during testing. It is designed for safe, controlled testing of battery seals without exceeding the manufacturer’s recommended pressure limits. 

The new kit is now available from Laser Tools stockists. For more information see the video below.
